In general,the code optimization and code-generation phases of a compiler,often referred to as the back end,may take multiple passes over the IR before generating the targer program.

如果需要使用一个寄存器但是这个寄存器存放其他变量，那么需要产生ST R，M来释放这个寄存器，这个过程称为register spill寄存器溢出

It may have a similiar efficiency with the normal type cyclone, so it can meet the requirment of the circulation in CFB but with the simple structure arreugement. With the process of experiment, such as misunderstanding of inner fluid structure in separators and the unadvanced surveying methods comcs obvious.

Results show this new-inlet hydrocyclone has original sides on liquid spin-making and stabilize its flow field. Moreover this gradual contraction inlet may translate some pressure energy of liquid into kinetic energy and increase circumrotate speed. These play active actions on improving separation efficiency. Moreover, the uniflow hydrocyclone has the traits of big capacity, low pressure drop and a little low separation efficiency in contrast to the returned flow hydrocyclone. This hydrocyclone system has the higher separation property in contrast to the single-level hydrocyclone.

The proposed algorithm can preserve invariability on the geometric structure: the eigenvectors which are neighboring each other in the original space will maintain the same attribute in low-dimensional space; on the contrary, the unsimilar eigenvectors become apart farther each other. Therefore, the description generated by our algorithm can show the interrelationship between features and has strong robustness.

所提出的算法能保持描述器之间的几何结构不变：原空间中邻接的描述器映射到低维空间后保持邻接，而不相似的描述器映射后区分度更大，所以该算法所生成的描述器能表现特征点之间的内在关系，具有很强的鲁棒性。

By Ensemble-averaged Method, the mean field was got to show the 3D structure of flow. By Phase-locked Averaged Technique, the periodic mean field was got to reflect the periodic unsteady characteristic. The 3D structure and the periodic unsteady characteristic of the unsteady flow within the vaneless and vaned diffuser were discussed through analyzing the mean field and the periodic mean field.

The predacious organs of the strain are annulus and cohesive nets and the hypha which is different from the vegetative mycelium. In the cytosol there are many electro-densities which are about circular particles in different size and array on the marginal area of the hypha cell of the predacious organs, this is the important character of the fungus.

菌株的捕食器为菌环和菌网，形成捕食器的菌丝细胞结构不同于一般的营养菌丝，胞质中含有许多电子密集体，呈大小不等的黑色类圆形颗粒状，多数排列在捕食器菌丝细胞的边缘区域，这是捕食线虫性真菌捕食器菌丝细胞的一个重要特征。

The contents of valine and leucine of the nematode are obvious higher than that of others in different kinds of amino acid of the nematode. The analysis of irritant factors playing a important role on the production of predacious organs showed that live nematode larva or its lytic solution can cause the production of predacious organs of the strain A1, but the latter produced less than the former .The live larva of the third stage produced more predacious organs than one of the first and the second stage , so the number of predacious organs that are produced by the live larva of first and the second the stage are less than the live larva of the third stage .

刺激捕食器产生的因素在线虫体来说：活的线虫幼虫和其裂解液可以刺激捕食线虫性真菌—少孢节丛孢菌菌株产生捕食线虫性结构——捕食器；但后者刺激产生的捕食器数量较少；有活力的第三期幼虫与第一、二期幼虫相比较，可以刺激菌株产生较多的捕食器；但少孢节丛孢菌对第一、二期幼虫作用速度快；与第三期幼虫相比，第一、二期幼虫易被捕获致死。
